BINDER ATTACHMENT.

SPECIFICATION forming part of Letters Patent No. 762.093, dated June 7', 1904.

Application filed February 18, 190 Serial No. 194,125. (No model.)

Tb all whom it may concern:

Be it known that 1, HENRY J. SOHWARZE, a citizen of the United States, and a resident of Verona, in the county of Lawrence and State of Missouri, have invented a new and Improved Binder Attachment, of which the following is a full, clear, and exact description.

This invention relates to an improved manner of mounting the cheek-springs of grainbinders, which are commonly arranged .to bear on the binder-deck to retard the grain during the formation and binding of the gavel.

Heretofore the check-springs have been mounted so that they cannot be adjusted except by the use of a wrench or equivalent tool for relaxing the spring-fastenings and adjusting each spring independently. By means of my invention the springs may be readily adjusted by the operator without leaving the seat of the harvester. This enables me to produce a properly-bound bundle irrespective of the condition of the grain, and it is well known that as the condition of the grain varies the check-springs must be adjusted accordingly.

This specification is adetailed description of one example of my invention, while the claims define the scope thereof.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the views.

Figure 1 is a side view showing the binderdeck and breastplate and illustrating my invention in operative position. Fig. 2 is a rear elevation of the invention, and Fig. 3 is a crosssection on the'line 3 3 in Fig.1.

10 indicates the binder-deck, 11 the breastplate, and 12 the breastplate-brace, which parts are common in grain-binders.

14 indicates the check-springs, which are here shown to be three in number, located over the binder-deck adjacent to the breastplate and needle, and are provided with fastenings 15, connecting them with a tubular rock-shaft 16. Said shaft extends horizontally and is mounted in a bearing 17, attached to the brace 12, and ma bearing-bracket 18, fastened to the shield 19 orto any other convenient stationary part of the binder. By rocking the shaft 16 the check-springs 14 may be adjusted toward and from the binder-deck. so as to vary the pres sure of said springs on the grain, and thereby enable the operator to bind auniform bundle irrespective of the varying conditions of the grain.

Means are provided foradjustably holding the rock-shaft 16. Preferably these means extend into the immediate proximity of the seat of the operator, and, as here shown, they comprise an arm 20, attached to the shaft 16 and connected by a link 21 with a crank 22. Said crank is carried by a rock-shaft 23, suitably mounted on the binder and extending longitudinally thereof. The shaft 23 terminates at its rear end in a hand-lever 24, provided with a dog 25, which coacts with a'quadrant 26, whereby the shaft 23 may be rocked from one position to another and held securely at the desired position. In this way the shaft 16 may be rocked, as before explained, and held in any desired adjustment.

In order to enable the binder mechanism to be shifted to suit the length of the grain, the shaft 16 has a slot 16 therein and the arm 20 is extended loosely through the slot. Said arm is also held loosely in a slot 18 in the bracket 18, and in this manner the parts 11, 12, 17, 16, and 14 may be shifted at will without disturbing the means for rocking the shaft 16.

Various changes in the form, proportions, and minor details of my invention may be resorted to at will without departing from the spirit and scope thereof. Hence I consider myself entitled to all such variations as may lie within the intent of my claims.

Having thus described my invention, I claim as new and desire to secure by Letters Patent 1. The combination with a grain-binder, of a check spring or springs located over the binder-deck adjacent to the breastplate, means for mounting the same, and means for adj usting the same, the latter means extending into proximity to the seat of the operator to enable the tension of the check-springs to be adjusted by the operator on the seat, for the purpose specified.

2. The combination with a binder, of a rockshaft, means for mounting the rock-shaft, a check-spring attached to the rock-shaft, and located over the binder-deck adjacent to the breastplate and means for adjustably holding the rock-shaft, the latter-means extending into proximity to the seat of the operator, for the purpose specified.

3. The combination with a self-binding harvester, of a check-spring located over the binder-deck adjacent to the breastplate, means for mounting the same to be bodily 'shiftable With the binding mechanism, said means including a slotted rock shaft carrying the spring and means for adjusting the tension of the spring independent of said shifting movement; thelast-named means including an operating member bearing loosely in the slot in the rock-shaft.

4:. The combination With a binder, of a rockshai't mounted thereon, a check spring or springs attached to the rock-shaft, andlocated over the binder-deck adjacent to the breastplate, a crank in connection with the rockshaft, a link attached to the crank, a second rock-shaft having a crank connected with the link, the second rock-shaft extending into proximity to the seat of the operator, and

means adjacent to the seat, for adjustably holding the second rock-shaft.

5. The combination With a self-binding harvester, of a cheek-spring located over the binder-deck adjacent to the breastplate, means for mounting the same to be bodily shiftable With the binding mechanism, and a relatively stationary means for adjusting the tension of the spring, the latter means having connection With the spring to adjust the same irrespective of its shifting movements.

6. The combination With a self-binding harvester, of a check-spring located over the binder-deck adjacent to the breastplate, means for mounting the same to be bodily shiftable with the binding mechanism, and a relatively stationary means for adjusting the tension of the spring, the latter means having sliding connection with a part of the spring-mounting means for the purpose specified.

In testimony whereof I have signed my name to this specification in the presence of two subscribing Witnesses.

HENRY J. SGHWVARZE.
